WATER-GATE.

:LEIGIFICATION forming part of Letters Patent No. 328,897, dated Qctiober 20,41885.

Application filed December 3, 1884. Serial No. 149,399. (No model.)

To @ZZ whom it may concern:

Be it known that I, WILLIAM A. LovELAoE, of Lovelaceville, in the county of Ballard and State of Kentucky, have invented a new and Improved Tater-Gate, of which the following is a full, clear, and exact description.

The object of my invention is to provide a simple, inexpensive, and efficient water-gate to prevent live-stock trespassing on adjacent lands, and one which will be lifted automatic ally by the rising water, and so as to be clear of floating substances drifting down stream with the iiood.

The invention consists in a water-gate constructed Vwith the gate proper made in two sections hinged horizontally to each other and guided along hollow posts having` bottom openings for inlet of water to lift floats held in the posts and connected to the gate to raise it as the water rises, together with chains or cords connected to the hinged lower gate-section and passing over the upper gate-section and iiXed to the banks of the stream or to the gateposts at the front of the gate.

The invention consists,also,in particular constructions and combinations of parts of the gate, all as hereinafter fully described and claimed.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in both the iigures.

Figure l is a sectional elevation of my improved watcr-gate at the upstream side, and Fig. 2 is a cross-sectional elevation taken on the line x w, Fig. l.

I make the water-gate proper in two sections, an upper section, A, consisting of side posts a and cross-bars a', and a lower section, B, consisting of side posts b and cross-bars b', and I hinge the two parts A B to each other by hinges C of any approved kind.

The letters D D indicate two hollow posts or standards, which are fixed to the opposite banks E F of the stream G or water-course in which'the gate is to be set up, and a fiume will preferably be built up at the opposite banks for some little distance at each side of the gate-posts D D-say, by setting the planks H against the banks and securing them in any approved way.

The posts D D have openings d at or near their lower ends which rest on ,the bottom of the water course, said openings preferably facing upstream, so that the water flowing downstream will enter the posts D D and raise the floats I I, which have angle-arms J J connected to them, the upper endsj of said arms J J being bent outward and extending through slots K K of the opposite posts D D and connected to the lower ends of the opposite side bars c a of the upper gate-section A, and L L are guide studs or blocks fixed higher up on the gate-bars c a, and also entering the slots K K of the posts D D, and serving with the parts j j of the float-arms to hold the gate-section A upright as the gate is raised and lowered by the rise and fall of the floats I I as the water rises and falls.

As seen best in Fig.2, the gate A B is placed so that its lower section, B,will swing open on the hinges C downstream or in direction ofthe arrow M.

To the lower ends of the side posts b b of the hinged gate-section B are attached the one end of chains, ropes, or cords N N, pref i erably chains, which pass upward to and over pulleys or sheaves O O, journaled at the tops of the side post-s a a of the gate-section A, and thence downward in front of the gate to connect at p p with the ends of arms or brackets P I), fixed to the planking II to the opposite banks of the stream or to the gate-posts.

It is evident that as the gate A B is lifted by the rising water acting on the floats I I, the chains N N will be drawn upon by the gatesection A, and the connections at l? I? being unyielding or fixed, the lower gate-section, B, will be swung back bythe pull of the chains, so that its lower edge or cross-bar shall always be lifted a sufcient distance above the surface of the rising water to allow drift-wood or other substances usually carried down stream by floods to pass along beneath thev gate without striking and injuring it; and as the flood subsides and the water falls the floats I will fall and the gate with them, and the lower gate-section, B, will gradually close into line with the upper gate-section, A, as will readily be understood.

By connecting the chains N N to section B, nearer to or farther from the hinges C, the

IOO

section B will be swung open quicker or more slowly, as may be required in any particular locality, to be lifted above the substances usually floated downstream by the flood.

I show the side posts D D made of four boards or planks nailed together and stood on end; but the posts may be made of sheet or cast metal,and in round or other form,with the water-inlets at or near their lower ends, and the guide-slots for the upper gate-section, A.

The drawings represent the Watergate, set in the stream or water-course next to a fence, consisting of posts R and wires S strung on the posts, so that cattle or live-stock cannot pass either way, up or down stream,to trespass on neighboring lands.

The gate-sections may be made of wooden posts and cross-bars, as seen by section A, or of wooden posts and wood and metal cross-bars, as seen by section B, or of any other suitable light and strong materials.

- It will be understood that the chainsN may be attached to the gate-posts D near the pulleys O by brackets P or otherwise, so that the connections of chains N at the front of the gate shall always be above hi gli-water 1nark,to prevent the chains heilig carried away by floating objects, and thus disabling the gate.

Having thus described my invention, what I claim as new,and desire to secure by Letters Patent, is-

l. In a lwater-gate, the combination, with hollow posts having bottom openings, of a verticallysliding gate composed of two hinged scctions,iioats in the said posts, and connected to the upper gate-section,and means for swinging backward the lower gate-section as the gate is lifted by the floats, as setforth.

2. In a water-gate, the combination, with hollow posts having bottom openings, of a gate composed of two hinged sections guided on the posts, floats in the said hollow posts, and connected to the upper gatesections, and chains connected to the lower gate-section, passing over the upper section, and secured to a fixed support,substantially as'herein shown and described.

3. The combination,in a water-gate, of the gate-sections A B, hinged to each other at C, the hollow postsD, having bottom openings d and slots K., andthe floats I, moving in posts D, and connected by arms .I with the side posts a a of the upper gate-section, A, substantially as herein set forth.

4. The combination, in a water-gate, ofthe gate A B C, posts D, having openings d, and slots K, iioats I, arms J, passing through the slots K, and connected to the gate-posts a, and the guidestuds L on the posts a, also entering the slots K, substantially as herein set forth.

5. The combination, in awatergate, of the gate A B C,the posts D, having openings, d and slots K, the floats I, connected by arms J to the gate-section A, the guidestuds L, and the chains N, connected to gate-section B, passing over pulleys O at the top of gate-section A, and fastened to the banks or to the gate-pests at the front ofthe gate, substantially as herein set forth.
